Thanks for posting your query.

If you have questions after reading my answer, be sure to let me know.
First thing I would like to tell you is as long as the growth and development of your son is within normal range, it is unlikely that he is having any serious underlying chronic disease.
Occasional congestion could be due to infections. Most often it is due to viral infections and are self limiting.
If there is persistent of symptoms with a history of baby eczema, the congestion and cough can be due to allergic disease. Most often it presents as bronchiolitis with fever
, runny nose
and cough and are self limiting.
You have made a mention that when he takes more than a few bites he makes funny sounds and that he often spits up. These could be due to gastroesophageal reflux. This is a normal phenomenon seen in babies and occurs due to the stomach content refluxing in to the foodpipe. This usually resolves around 8-10 months of age when babies starting sitting with or without support.
So as said in my first line as long as the growth and development are within normal range, there is no need to worry.
Let me know if I can assist you further.
